<DT><B>Description</B><DD>
getmaxcolor returns the highest valid color value for the current graphics driver and mode that can be passed to setcolor.
<P>
For example, on a 256K EGA, getmaxcolor always returns 15, which means that any call to setcolor with a value from 0 to 15 is valid. On a CGA in high-resolution mode or on a Hercules monochrome adapter, getmaxcolor returns a value of 1.

<P><DT><B>Windows Notes <IMG SRC="win.gif" ALT="[WIN]"></B><DD>
The <A HREF="../../bgi/README.html">winbgim</A> version of
getmaxcolor returns
15 for the
maximum color. However, in addition to the usual BGI colors (0 through
15), the programmer may also use 
<A HREF="wincolor.html">RGB colors</A>.

<P><DT><B>Return Value</B><DD>
getmaxcolor returns the highest available color value.
